I have an 02 4.6 liter F-150 Supercab. I was only getting 16 mpg when I bought it. When I took it in, the service geniuses told me that it is the "breaking in period". I have never gotten anything different since... I know part of it is that I drive 69 mph on the freeway.

I thought that was about tailgate up or down (results: no difference). I don't think Chevy would install a tonneau on its Silverado mileage leader, unless it was actually doing something to help mileage.

I have a '97 Ford F-350 pickup, 4x4 with a 5.8 v8 auto trans. The truck only has 54,000 miles on it and it in good shape. Does anyone know if I can do anything with the gas mileage? I average betweem 7 and 9 mpg all the time. The truck will pull a house with the 4.10 gears. I've done a k&n filet, 3" exhaust, synthetic fluids all the way around.

I have a 1999 f-250 super duty, 7.3, that gets about 17mpg around town when I'm not towing. I pull a 5000lb camper, pull behind, with a 700 lb motorcycle in the bed, and then the mpg drops to 11mpg. I bought the truck used, so I don't know that much about it, Its got about 170,000 miles on it. Anybody know what could cause that much drop in mpg. My little f-150 towed the same camper and got 10.3 mpg.

Try checking your tongue weight. Instead of towing the weight you may be carrying the weight.Carrying instead of pulling the weight can cause a huge drop in economy.The same wil hold true if you have a fifth wheel trailer.

Okay geniueses.The question of the day is if you can drop the engine RPM by 100,200,300 how much econo change can you expect to get.This may be possible and still maintain 70 MPH,on the big road.Have a couple of ideas, that I am pretty sure can achieve the RPM drop.Does anyone know how much difference the drop will make?

Hello, I have the same 1997 truck (mine only has 87,000 miles) and it is a 4 door with the 460 engine...it has always been around 10 mpg or maybe 11 if truck is empty. I have owned it since 1999 and now this year it gets 4mpg and maybe 5 mpg if I really baby it along and dont idle at all in cold weather...what is the deal? did you ever hear what might be the cause? I have done regular maintemance....am now going to replace all plugs, wires, distributor cap fuel filter, etc. and see if that makes any difference....please email me if you have any ideas. Thank you

I will be purchasing an f-150 extended or crew cab truck in the next month. I'm just not sure if I want an 4x4 or 2x4. My situation is I drive around 4-5 k miles per month. I live in the mtn's of NC and fight snow and bad weather but I already have two 4x4 f-series trucks. Should I get a 4x4 or a 2x4? If weather is bad I can drive one of my less dependable trucks? But is the lack of maintnance and better gas mileage going to over throw the luxury of 4x4? Thanks, this decission is driving me nuts. Is anyone in the same boat, or just have a bone to throw?

This maybe too late to help you but I just bought a 2010 F150 Super Cab 3 weeks ago with the 5.4 lt. V8 and maybe it helps you or helps someone like you or me who wants to buy a new truck. We just went on a trip to Cali. from Seattle last week and planned about 2000 mi. My truck was/is brand new and I really really love it. I was worried about the gas mi. since my last one was a 2006 F150 4.6 Super Crew and the gas mi. was not great 2 WD as well. I got 18+ miles per gallon. It also seemed to improve as the trip went on. The trip computer only went as high as 16.2AVG miles per gallon but filled it when we left without topping off and filled it again without topping off at the first half tank in OR. 36 gal tank and at half a tank I put in 18.23 gals. I got 323 miles on the first half tank so it was approx. 18 mi. per gallon. Take into acct. that I don't have a topper or toneau cover and no extras. I was pretty pleased. So I got about 640ish miles on single tank. I was also carrying about 1000 lbs of gear, not much but if I put a cap on it I bet I will get closer to 20. Also I seemed to do better around 75 mph. cruising about 70 to 80 was only a diff. of about 150 to 200 rpm.

Try calculating your fuel mileage by fillups, not by the dash readout. You'll find that you're only getting about 15 at best. I have a 2005 F250 Lariat FX4 6.0 with EGR delete, AFE Stage2 intake, Magnaflow 4" turbo back exhaust, 3.73 rearend, Amsoil synthetic front to back and I still can't make 16MPG. My dashboard readout will show from 18-24MPG but fillup calculations come out to 14.5-16. If your numbers are fillup calculations I have to say you got a diamond in the rough because the 6.0's are notorious for bad fuel mileage, worse than the 7.3's, and the 6.4's are even worse at 9-12.5MPG. Good luck with your mods. Some words of advice, go with SCT programmer, do not use K&N filters use AFE, AEM, Banks filters, get an EGR delete kit, a 4" exhaust system, and an ARP head stud kit is imperrative with these mods or you will be blowing head gaskets. This is from experience so trust me.

What is the rear end on this truck, I have 4.10 and it gets about 12.5 to 13.5 empty. Most of my driving is between city and highway. I realy drive highway but when I do I get somewhere between 14-16.5 (I only ever got 16.5 when the truck was brand new....driving it home from the dealer...and back down to pick up the car I used to pick it up in.

I have a 2011 F150 Supercab with the 3.7 L. V6. I got that because I don't need heavy towing capacity and I was hoping for somewhat better gas mileage. I am usually pretty good at getting the estimated mileage on vehicles, if it is possible. Rather than 17/23 I am seeing more like 15/19 at best with an overall average of approx. 17. Is anyone getting anything close to the mileage they state for this V6? ronnoc

I just drove 286 miles (all highway) on less than half a tank. With about 20 miles until empty, as per my mileage calculator on my dash.

That's above 20mpg highway. My dash mileage monitor said 22.1, and I'm inclined to believe that isn't far off, because of the distance I traveled without having to fill up. I was astonished that I didn't have to stop to fill up dozens of miles before I did.

Averaged 60-70mph the whole way. Relatively flat (Rt. 95 from Maryland to Connecticut), but it is riddled with toll booths, so room to improve on mileage even.

And mine is the 4x4, Supercab, and the gear ratio is 3.73.

Not making this up. 20++ mpg highway out of a stock 4WD version of the EcoBoost F150.

I'm a bit of a light-foot (I like vehicles with ample power, so I don't always have to rev them). So I'll bet I could get ~24mpg out of a 2WD Ecoboost equipped Fun-50 from Florida to Maine, traffic and weather permitting.

GM says they are not worried about this engine, but they are underestimating its capabilities!

Just finished a 465 mi round trip from Maryland to Virginia with mostly light traffic, mid 70's outside temp, running 65-70mph, A/C off, no load. Averaged 18.1 mpg calculated. Mine has the Goodyear Wrangler off-road tires (like the FX4) and HD tow package. I cleared the trip computer and ran it about 200 miles with the computer reading 19.8 to 20.1 mpg, but I don't go by that for real world numbers. I typically get 10-11 mpg towing a 6,000lb camper that has 80 sq ft of frontal area. Luv this truck!

Just finished the first tank of fuel (Dealer supplied) and got 17.8 mpg this was 50/50 driving and about 50 miles of it was stop and go traffic not getting above 5mph. I am happy with this tank but am pretty sure I will average on the positive side of 20 mpg. The computer said 18.5 so it was not too far off. I almost bought the 3.7 V6 but after seeing the mpg that they are reporting I opted for the 5.0 I also looked at the Eco-boost but would of lost some serous rebate money. I think the 5.0 is so close in mpg to the Eco-boost that it is a wash plus this 5.0 takes me back to my GT Mustang days.

3rd tank same driving conditions 18.5 computer said 18.9 When driving the highway I am getting 21mpg but the city stop and go just kills the overall mileage for the tank. I now have 1400 miles on the truck so I will update when the engine gets broke in.
